2(1) Orbital piliferous punctures minute, mostly separated by distinctly more than their own diameters..…..……… sipylus
2’ Orbital piliferous punctures larger, separated by about their own diameters …..……………………………………..….…… sp. 1

Sp. 1: Alameda, Contra Costa, Lassen, Los Angeles, Modoc, Napa, Riverside, San Bernardino, Shasta, Sierra, Solano, Stanislaus, Tuolumne (RLZC, UCF, UCR). Most specimens have the body all dark (except the metasoma yellow basally). A few specimens have the mesosoma partially yellow, and previously I considered these as a separate species, but I can find no reliable morphological differences and now treat them as different color forms of the same species.
